我花了几个小时的时间才成功地安装了'pg' gem,最终我输入了 sudo env ARCHFLAGS="-arch x86_64" gem install pg -v 0.12.2 -- --with-pg-config=/Applications/Postgres.app/Contents/MacOS/bin/pg_config
,这个方法非常好用。但是现在我在尝试使用 bundler 时仍然遇到同样的错误,所以我猜我并没有真正解决问题?无论如何,这里是 bundle install
的报错信息:

我认为问题在于bundler尝试使用已删除的另一个postresql安装中的pg_config来安装宝石。 有没有办法确保bundler使用正确的路径?
bundle install
之前运行bundle config build.pg --with-pg-config=/Applications/Postgres.app/Contents/MacOS/bin/pg_config
